High-light-effect tree shape shaping trimming method for close planting peach trees

Abstract

The invention discloses a high-light-effect tree shape shaping trimming method for close planting peach trees. A concrete method comprises the following steps that after the nursery stock planting, the stem determination is carried out in a 40-50cm position, and when new branches grow to 20cm, a straight healthy and strong new branch is selected from the top end to be used as a new branch for culturing a central stem. Two staggered opposite uniform-growth-vigor new branches extending to positions between lines are selected under the central stem main branches to be used as main branches, the rest long branches are subjected to branch taking so that the rest branches are in a horizontal shape, the growth vigor is controlled, the branch mature and the flower bud satiation are prompted, and the early fruiting is promoted. The rest medium and short branches all keep untreated. During the shearing in winter, the central stem extending branches are sheared for remaining 40 to 50cm, the main branches are cut at a position about 50cm, and in addition, one lateral sub branch is selected from the lower part to be cut. The shaping is still carried out according to the method in the second and third years, and the shaping task is basically completed. The high-light-effect tree shape shaping trimming method for close planting peach trees provided by the invention has the advantages that the shaping speed is high, the light illumination is good, the blossoming and fruiting are early, the yield is high, the quality is good, and artificial or mechanical operation and management are convenient.

Description

technical field [0001] The invention relates to a method for shaping and pruning fruit trees, in particular to a method for shaping and pruning densely planted peach trees with high light efficiency. Background technique [0002] Peach trees are light-loving trees. The shape and structure of peach trees directly affect the distribution of light in the canopy, photosynthetic productivity, flower bud formation, flower bud quality and branch life, which in turn affect the yield and quality of fruits. At present, the tree shapes used in China include the natural happy shape with a large canopy, the natural spindle shape that can be planted closely, and the improved spindle shape and other trunk shapes. In the early stage of the happy shape, the yield is low and the forming is slow. From the full fruit stage, due to the large amount of nutrients flowing to the top of the crown and the fruit, the base of the tree cannot be supported by the leaves for a long time. The base is bare...
